Immunocytochemical evidence for the presence of Met-enkephalin and Leu-enkephalin in distinct neurons in the brain of the elasmobranch fish Scyliorhinus canicula.

, 1994
Immunohistochemical methods have been used to investigate the distribution of various opioid peptides derived from mammalian proenkephalin in the central nervous system of Scyliorhinus canicula.

Delta Opioid Receptors and Enkephalinergic Signaling within Locus Coeruleus Promote Stress Resilience

Brain Sciences, 2022
The noradrenergic nucleus locus coeruleus is a key component of the stress circuitry of the brain. During stress, the neuropeptide corticotropin-releasing factor (CRF) is secreted onto LC, increasing LC output and norepinephrine concentration in the ...

Neuropeptide System Regulation of Prefrontal Cortex Circuitry: Implications for Neuropsychiatric Disorders

Frontiers in Neural Circuits, 2022
Neuropeptides, a diverse class of signaling molecules in the nervous system, modulate various biological effects including membrane excitability, synaptic transmission and synaptogenesis, gene expression, and glial cell architecture and function. To date,

Automation of the Azapeptide Submonomer Synthesis Method [PDF]

J Pept Sci
The solid phase submonomer azapeptide synthesis method was automated using a commercially available peptide synthesizer. Key findings for the successful automation included the use of stable isocyanate precursor for the semicarbazone installation step, elimination of all cooling steps, use of a heating block, and use of DMF as solvent.

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

Plant, Cell &Environment, Volume 49, Issue 12, Page 9694-9710, December 2026.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

Radioimmunological and immunocytochemical demonstration of met-enkephalin in planaria

, 1983
1. An anti-Met-enkephalin serum has been used for radioimmunological and immunocyto-chemical demonstration of Met-enkephalin in planaria. 2. The serum showed a high degree of sensitivity and specificity. 3.
